They gave me the number of another company. I explained the issue to the fellow over the phone and he came out with a very large air compressor mounted on a trailer. he first probed for the drain lines and then marked them with little metal flags. He then started the compressor and pushed the small diameter pipe into the ground. He opened a valve on the pipe and air flowed into the ground and you could see it visibly raise in about a 2 - 3 foot circle around his pipe. He worked over the whole drain field in this manner. He said that the idea was that the lifting of the biomass with the compressed air tended to break it up and, sure enough, our drain field began draining again.
The local company we used called it 'High pressure water jet' service from the D-box out to the drain field. Then they added 1 case of 'Septic Scrub Treatment'.
Total cost, which also included pumping out our 300 gallon tank and the D-box, and replacing the baffle was $1,620 last May. It passed inspection and we moved in November.
